A randomized controlled trial of a structured exercise intervention after the completion of acute cancer treatment in adolescents and young adults

Identifying Adolescent and Young Adults' Preferences for Oncology Symptom Management Clinical Trial Participation

BACKGROUND

Most studies to date exploring facilitators and barriers to adolescent and young adults' (AYAs') participation in clinical trials have been focused on external factors to AYAs' participation or recruitment strategies.

OBJECTIVE

The purpose of this mixed-methods study was to determine AYA cancer survivors' preferences for oncology symptom management clinical trial participation.

METHODS

Semistructured interviews and conjoint analysis were conducted to clarify potential attributes (eg, characteristics) and levels (eg, value of the characteristic) that may be important to AYA cancer survivors when considering clinical trial participation (n = 19). The final list of attributes and levels was administered within a choice-based conjoint analysis survey (n = 52). The utility score for each level was analyzed using hierarchical Bayes estimation, and the feature importance for each attribute was quantified.

RESULTS

The type of new treatment (22.9%) and perceived importance of study topic (19.5%) were the most important attributes identified by participants. The levels with the highest utility scores within each attribute included prescription medicine treatment with mild side effects, electronic surveys, under-30-minute study visits, no follow-up visits, 4-week treatment period, and once-a-week treatment frequency.

CONCLUSION

The data support that study designs with low participant burden, interventions with few side effects, and the involvement of AYAs in determining the priority of the research topic are appealing to AYAs when considering participation in symptom management trials.

IMPLICATIONS FOR PRACTICE

AYA participation in clinical trials is necessary to develop new symptom management modalities. Clinicians may use the results to introduce clinical trials containing trial characteristics that appeal to AYA cancer survivors.

Feasibility of telehealth exercise and nicotinamide riboside supplementation in survivors of childhood cancer at risk for diabetes: A pilot randomized controlled trial

BACKGROUND

Childhood cancer survivors (CCS) have a 50% higher risk of diabetes mellitus (DM) compared with the general population. Interventions in survivors with prediabetes (fasting glucose 100-125 mg/dL or hemoglobin A1c 5.7%-6.4%) may mitigate the development of DM and its attendant morbidity, but there is limited information on the feasibility of secondary prevention in this setting.

METHODS

This 6-week pilot feasibility 1:1 randomized controlled trial enrolled 20 CCS on a structured telehealth exercise program ± nicotinamide riboside (NR), a nicotinamide adenine dinucleotide precursor. Feasibility metrics were: (1) ≥50% of eligible CCS enrolled onto study; (2) ≥70% of participants completed baseline and end-of-study assessments; (3) ≥70% compliance with exercise and NR. Secondary endpoints included changes in biomarkers associated with glucose homeostasis and muscle health.

RESULTS

Median age (years) at cancer diagnosis was 16.5 (range, 1.5-21.5) and 35.5 (range, 18.0-67.0) at study enrollment. Enrollment rate was 87%, and 85% of participants completed baseline and end-of-study assessments. The mean percentage of exercise sessions completed was 86.6%; NR compliance was > 90%. There were no severe adverse events attributable to study interventions. Secondary endpoints were not significantly different between study arms at study completion. Myostatin decrease was observed in participants who completed a higher median number of exercise sessions and was associated with decreased intramuscular adipose tissue and increased lower extremity muscle cross-sectional area.

CONCLUSIONS

A telehealth exercise intervention ± NR supplementation was feasible in CCS with prediabetes. Future studies in larger cohorts may be needed to evaluate their beneficial effects on muscle health and DM risk among CCS.

Exploring Adolescent and Young Adult Cancer Survivors' Experience with Cancer Treatment-Related Symptoms: A Qualitative Analysis of Semi-Structured Interviews

Purpose: Few studies have specifically targeted symptom management interventions for adolescent and young adult (AYA) cancer survivors. A greater understanding of AYA cancer survivors' experiences with cancer treatment-related symptoms would help develop age-appropriate oncology symptom management interventions. The purpose of this qualitative analysis was to explore AYA cancer survivors' experience with cancer treatment-related symptoms. Methods: Nineteen post-treatment AYA cancer survivors (18-39 years old) who self-reported moderate-severe cancer treatment-related symptom severity participated in video conferencing or telephone interviews. The questions in the interview guide queried participants to share their experience with cancer treatment-related symptoms. Inductive content analysis was used to identify themes from the interviews. Results: The themes that emerged from the interviews included (1) cancer treatment-related symptoms negatively affected AYA cancer survivors' quality of life (e.g., symptoms served as a reminder of cancer recurrence possibility); (2) AYA cancer survivors' attitudes and feelings about communicating cancer treatment-related symptom concerns to clinicians (e.g., patient-clinician communication was bolstered when AYAs perceived that symptoms were being taken seriously); (3) AYA cancer survivors are interested in oncology symptom management clinical trials, but logistical challenges are barriers to participation; and (4) AYA cancer survivors are interested in nonpharmacological treatments for symptom management. Conclusion: Results highlight the burden of cancer treatment-related symptoms on day-to-day life among post-treatment AYA cancer survivors. Future work is needed to identify nonpharmacological symptom management interventions, strategies to improve patient-clinician communication about symptoms, and strategies to increase the visibility and accessibility of symptom management clinical trials for AYA cancer survivors.

Current evidence of integrative oncology modalities for managing adverse effects and survivorship issues among adolescents and young adult (AYA) cancer patients and survivors

PURPOSE OF REVIEW

Symptom burden of cancer diagnosis and treatment has led adolescents and young adult cancer patients (AYAC) and survivors to seek different self-management strategies including integrative oncology (IO) modalities. IO holds great promise to improve survivorship issues in adolescents and young adult (AYA) cancer survivors. This review aims to encompass the current evidence of IO modalities and to analyze the efficacy of IO for managing survivorship issues among AYA cancer patients and survivors.

RECENT FINDINGS

Nineteen randomized controlled trials included in this review evaluated mind and body modalities including both physical and psychological (74%) and psychological only (26%) modalities. Most assessed IO modalities were physical activity (PA) (37%) and structured exercise (10%). Most effective IO modalities found were PA, massage, mindfulness-based stress reduction (MBSR) and light therapy for treating AYA symptom burden. The Cochrane risk of bias (RoB-2) concluded 21% studies had high risk, 58% possessed some concerns and 21% had low risk.

SUMMARY

Although evidence has shown that a number of IO modalities may improve survivorship among AYA cancer survivors, more rigorous study designs are needed in order for these modalities to be routinely recommended for use in clinical practice.

A Systematic Review of the Characteristics and Effects of Physical Activity Interventions on Physical Activity Engagement, Long-Term and Late Effects, and Quality of Life in Adolescent and Young Adult Cancer Survivors

Physical activity (PA) may minimize long-term and late effects experienced by cancer survivors. However, the efficacy of PA interventions in increasing PA engagement among adolescent and young adult (AYA) cancer survivors diagnosed between 15 and 39 is not well understood. This systematic review aimed to examine the effects of moderate- to high-intensity or strength training PA interventions on PA engagement in AYA cancer survivors. Secondary aims included describing intervention components unique to efficacious interventions, identifying symptom management in PA interventions, and evaluating intervention effects on quality of life (QoL), and long-term or late effects of cancer. We searched PubMed, CINAHL, PsycINFO, SportDiscus, Cochrane Library, and Scopus databases from inception to August 2022 and identified 12 articles, including 8 randomized controlled trials and 4 quasi-experimental studies. The effect of PA interventions on PA engagement was mixed, with four studies reporting increases in PA engagement ranging from 18.4 to 113.8 min/week postintervention. There was great diversity in PA intervention components. Motivational interviewing, supervised and unsupervised PA sessions together, moderate-intensity PA only, and mindful meditation were components unique to efficacious interventions. No intervention incorporated symptom management components. Studies provided some evidence of PA interventions on potential long-term effects of cancer, with positive impact on fatigue, and some evidence of improved anxiety, sleep, and QoL. Given limited research with AYA cancer survivors, additional research is needed to identify effective intervention components, integrate symptom management strategies into PA interventions, and track effects of PA interventions on late and long-term effects of cancer in this population.

Interventions about physical activity and diet and their impact on adolescent and young adult cancer survivors: a Prisma systematic review

PURPOSE

Over the past few decades, the incidence of cancer among adolescents and young adults (AYA) has been increasing. The impact of behaviors, such as physical activity (PA) and nutrition, on disease progression, prognosis, and overall health and quality of life for AYA cancer survivors is of significant importance. This systematic review aims to evaluate the effectiveness of PA and diet interventions for AYA cancer survivors and to critically evaluate existing literature, gaps, and limitations.

METHODS

A search of literature was conducted in PubMed, Science Direct, Scopus, and Google Scholar following the PRISMA guidelines. Twenty-two studies were included from online databases from 2012 to 2022, 13 of which were randomized controlled trials.

RESULTS

Most interventions were related to PA, with only four studies including nutrition or Diet interventions. The interventions were generally feasible and acceptable to AYA cancer survivors, and digitally based PA interventions were commonly used. PA interventions mainly comprised aerobic and resistance training and were individualized. Overall, this review found various PA and diet interventions for AYA cancer survivors that were feasible and well-accepted, but gaps in knowledge and design still exist.

CONCLUSIONS

This systematic review underscores the importance of conducting more research on diet interventions for YCS. PROSPERO REGISTRATION: https://www.crd.york.ac.uk/prospero/#aboutregpage.

Patient Reported Fatigue Among Adolescent and Young Adult Cancer Patients Compared to Non-Cancer Patients: A Systematic Review and Meta-Analysis

Adolescent and young adult (AYA) cancer patients and survivors are a growing population due to more frequent diagnoses and improved survival. Fatigue is a common symptom experienced by cancer patients and it is often missed by health care professionals. Patient reported outcome measures (PROMs) can assist in evaluating patient reported fatigue. This systematic review aims to determine if AYA cancer patients report more fatigue than AYAs who have not been diagnosed with cancer. We used a subset of articles from a larger review that searched PubMed, EMBASE, CINAHL, and PsycINFO to determine which PROMs and domains are currently being used to evaluate AYA cancer. This study identified 175 articles related to PROMs in the AYA cancer population. Articles with PROMs reporting on fatigue/vitality were used in this review. From the original 175 articles, we identified 8 fatigue/vitality articles for this review. All eight articles found an increase in fatigue/decrease in vitality in the AYA cancer population compared to healthy controls. A meta-analysis was performed on four articles that used the same PROM tool (EORTC QLQ-C30). This found a statistically significant and clinically meaningful increase in mean fatigue of 12.5 95% confidence interval: 3.3-21.8 points (scale 0-100, higher number indicates more fatigue) in the AYA cancer group compared to healthy noncancer controls. Fatigue in the AYA cancer population is a significant issue, it is often undetected and underreported, and early interventions are needed to prevent the negative subsequent sequelae.

Physical Activity Intervention Characteristics and Effects on Behavioral and Health-Related Outcomes Among Adolescents and Young Adults Living with and Beyond Cancer: A Systematic Review

Participation in physical activity (PA) during and after cancer treatment is safe and beneficial in the adolescent and young adult (AYA) cancer population. PA can positively impact health-related outcomes; however, participation remains low. This systematic review aims to describe PA intervention characteristics and outcomes in AYA survivors of cancer (AYASCa). This review followed Preferred Reporting Index for Systematic Reviews and Meta Analyses (PRISMA) guidelines and was registered with Prospero (CRD42022365661). PubMed, CINAHL, and Scopus databases were searched for randomized control trials (RCTs) and pre/post-test studies without a control group through December 31, 2022. Data included: participant demographics, PA intervention characteristics, and health-related outcomes. Studies were assessed using the National Institute of Health Critical Appraisal Tools, and findings were synthesized to identify common characteristics of PA interventions and outcomes. Twenty-three studies were included: 15 RCTs and 8 pre/post-test studies. Heterogeneity existed across design, sample demographics, intervention timing, and observed outcomes. The most common characteristics of PA interventions were supervision of PA, wearable device use, tailored/individualized PA prescriptions, and goal setting. PA interventions positively affected health-related outcomes, with 21 studies reporting statistically significant findings. Implementing personalized PA prescriptions, utilizing wearable devices, and incorporating goal setting as characteristics in PA interventions hold potential benefits for AYASCa, leading to improved outcomes. Still, additional research is needed to explore interventions that utilize these PA characteristics and determine which ones are most effective for AYASCa. By further investigating and identifying optimal PA characteristics, interventions can be better tailored to meet this population's specific needs and preferences, ultimately enhancing their overall well-being and recovery.

Physical activity and physical fitness assessments in adolescents and young adults diagnosed with cancer: a scoping review

PURPOSE

This scoping review describes the assessment methodologies for physical activity (PA) and physical fitness assessments used in studies focusing on adolescents and young adults (AYAs) diagnosed with cancer.

METHODS

A search of the literature was conducted in PubMed, CINAHL, Web of Science, and Cochrane Library following the PRISMA-ScR statement. A total of 34 studies were included in this review.

RESULTS

PA was primarily assessed via self-reported questionnaires (30/34) either completed in-person (n = 17) or online (n = 13) at different time points and different stages along the cancer trajectory (i.e., from diagnosis onward). A total of 9 studies conducted a physical fitness assessment.

CONCLUSIONS

PA and physical fitness measurements are key when trying to describe outcomes, assess for associations, track changes, measure intervention adherence, and test intervention efficacy and effectiveness. Considerable heterogeneity across studies was reported limiting the generation of formal recommendations or guidance for researchers, healthcare providers, and policy makers.

Healthy lifestyle interventions for childhood and adolescent cancer survivors: a systematic review and meta-analysis

PURPOSE

This study investigated the effects of healthy lifestyle interventions (HLSIs) on health-related quality of life (HR-QoL) in childhood and adolescent cancer survivors (CACS).

METHODS

Major databases were searched for English-language original articles published between January 1, 2000 and May 2, 2021. Randomized controlled trials (RCTs) and non-RCTs were included. Quality was assessed using the revised Cochrane risk-of-bias tool, and a meta-analysis was conducted using RevMan 5.3 software.

RESULTS

Nineteen studies were included. Significant effects on HR-QoL were found for interventions using a multi-modal approach (exercise and education) (d=-0.46; 95% confidence interval [CI]=-0.84 to -0.07, p=.02), lasting not less than 6 months (d=-0.72; 95% CI=-1.15 to -0.29, p=.0010), and using a group approach (d=-0.46; 95% CI=-0.85 to -0.06, p=.02). Self-efficacy showed significant effects when HLSIs provided health education only (d=-0.55; 95% CI=-0.92 to -0.18; p=.003), lasted for less than 6 months (d=-0.40; 95% CI=-0.69 to -0.11, p=.006), and were conducted individually (d=-0.55; 95% CI=-0.92 to -0.18, p=.003). The physical outcomes (physical activity, fatigue, exercise capacity-VO2, exercise capacity-upper body, body mass index) revealed no statistical significance.

CONCLUSION

Areas of HLSIs for CACS requiring further study were identified, and needs and directions of research for holistic health management were suggested.

Physical Activity as a Treatment for Cancer-Related Fatigue in Children, Adolescents and Young Adults: A Systematic Review

Background: Cancer-related fatigue (CRF) is one of the most common and distressing symptoms in paediatric oncology. Based on previous studies, physical activity interventions are considered to be effective in reducing CRF in adult cancer patients. Aim: The aim of this systematic review is to investigate whether physical activity interventions can reduce CRF in paediatric patients undergoing cancer treatment. Methodology: A systematic literature search was conducted in PubMed and Sport-Discus in October 2021 to identify intervention studies examining the effects of physical activity on CRF in cancer patients ≤ 21 years of age. Their methodological quality was assessed using the JBI Critical Appraisal Tool. Results: A total of 20 studies (seven randomized-controlled, six quasi-experimental and seven single-arm intervention trials) were included in the review. Nine studies reported significant positive effects of physical activity interventions on CRF in group comparison or within groups. Eleven trials reported no significant changes in CRF. Conclusion: Physical activity as a therapeutic intervention in paediatric oncology may have the potential to reduce CRF in childhood cancer patients undergoing cancer treatment. Further high-quality studies with large samples are needed to verify these results and to assess the interdependence of dose and response of physical activity interventions.

Impaired aerobic capacity in adolescents and young adults after treatment for cancer or non-malignant haematological disease

PURPOSE

Childhood cancer survivors are at increased risk for cardiovascular disease. Maximal oxygen uptake (VO_2max) is a major determinant of cardiovascular morbidity. The aim of this study was to compare aerobic capacity, measured by cardiopulmonary exercise test (CPET), of adolescents and young adults in remission with that of healthy controls and to identify the predictors of aerobic capacity in this population.

METHOD

This is a controlled cross-sectional study.

RESULTS

A total of 477 subjects (77 in remission and 400 controls), aged from 6 to 25 years, were included, with a mean delay between end of treatment and CPET of 2.9 ± 2.3 years in the remission group. In this group, the mean VO_2max was significantly lower than in controls (37.3 ± 7.6 vs. 43.3 ± 13.1 mL/kg/min, P < 0.01, respectively), without any clinical or echocardiographic evidence of heart failure. The VAT was significantly lower in the remission group (26.9 ± 6.0 mL/kg/min vs. 31.0 ± 9.9 mL/kg/min, P < 0.01, respectively). A lower VO_2max was associated with female sex, older age, higher BMI, radiotherapy, and hematopoietic stem cell transplantation.

CONCLUSION

Impaired aerobic capacity had a higher prevalence in adolescents and young adults in cancer remission. This impairment was primarily related to physical deconditioning and not to heart failure.

TRIAL REGISTRY

NCT04815447.

IMPACT

In childhood cancer survivors, aerobic capacity is five times more impaired than in healthy subjects. This impairment mostly reflects early onset of physical deconditioning. No evidence of heart failure was observed in this population.

Physical activity and exercise for cancer-related cognitive impairment among individuals affected by childhood cancer: a systematic review and meta-analysis

BACKGROUND

Individuals affected by childhood cancer can have cognitive dysfunction that persists into adulthood and negatively affects quality of life. In this study, we aimed to evaluate the effects of physical activity and exercise on cognitive function among individuals affected by childhood cancer.

METHODS

In this systematic review and meta-analysis, we searched seven databases (CINAHL Plus, Cochrane Library, Embase, MEDLINE, PsycINFO, SPORTDiscus, and Web of Science) and two clinical trial registries (ClinicalTrials.gov and the International Clinical Trials Registry Platform) for randomised controlled trials (RCTs) and non-randomised studies of interventions (NRSIs) published (or registered) from database inception to Jan 30, 2022, with no language restrictions. We included studies that compared the effects of physical activity or exercise interventions with controls (no intervention or usual care) on cognitive function among individuals diagnosed with any type of cancer at age 0-19 years. Two reviewers (JDKB and FR) independently screened records for eligibility and searched references of the selected studies; extracted study-level data from published reports; and assessed study risk of bias of RCTs and NRSIs using the Cochrane risk of bias tool for randomised trials (RoB 2) and Risk Of Bias In Non-randomised Studies-of Interventions (ROBINS-I) tools, certainty of the evidence using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, and any adverse events. We used intention-to-treat data and unpublished data if available. Cognitive function was assessed by standardised cognitive performance measures (primary outcome) and by validated patient-reported measures (secondary outcome). A random-effects meta-analysis model using the inverse-variance and Hartung-Knapp methods was used to calculate pooled estimates (Hedges' g) and 95% CI values. We estimated the heterogeneity variance by the restricted maximum likelihood method and calculated I² values to measure heterogeneity. We examined funnel plots and used Egger's regression test to assess for publication bias. This study is registered with PROSPERO, CRD42021261061.

FINDINGS

We screened 12 425 titles and abstracts, which resulted in full-text assessment of 131 potentially relevant reports. We evaluated 22 unique studies (16 RCTs and six NRSIs) with data on 1277 individuals affected by childhood cancer and low-to-moderate risk of bias. Of the 1277 individuals, 674 [52·8%] were male and 603 [47·2%] were female; median age at study start was 12 (IQR 11-14) years, median time since the end of cancer treatment was 2·5 (IQR -1·1 to 3·0) years, and median intervention period was 12 [IQR 10-24] weeks. There was moderate-quality evidence that, compared with control, physical activity and exercise improved cognitive performance measures (five RCTs; Hedges' g 0·40 [95% CI 0·07-0·73], p=0·027; I²=18%) and patient-reported measures of cognitive function (13 RCTs; Hedges' g 0·26 [0·09-0·43], p=0·0070; I²=40%). No evidence of publication bias was found. Nine mild adverse events were reported.

INTERPRETATION

There is moderate-certainty evidence that physical activity and exercise improves cognitive function among individuals affected by childhood cancer, which supports the use of physical activity for managing cancer-related cognitive impairment.

A randomised controlled trial investigating the ability for supervised exercise to reduce treatment-related decline in adolescent and young adult cancer patients

Introduction

Exercise is recognised as integral in mitigating a myriad negative consequences of cancer treatment. However, its benefit within adolescent and young adult (AYA) cancer cohorts remains relatively under researched, and caution should be taken in extrapolating outcomes from adult and paediatric populations given AYA distinctly different physiological and psychosocial contexts. This study sought to evaluate the impact of an exercise intervention on mitigating the expected decline in fitness, strength, physical functioning, and quality of life (QOL) in AYA undergoing cancer treatment.

Methods

This prospective, randomised controlled trial (FiGHTINGF!T) allocated 43 participants (63% male, mean age 21.1 years) to a 10-week, multimodal, bi-weekly exercise intervention (EG) or control group (CG) undergoing usual care. Pre- and post-intervention assessments included cardiopulmonary exercise tests, one-repetition maximum (1RM) strength, functional tests, and QOL patient-reported outcome measures. Data were analysed via linear mixed models and regression.

Results

While no significant group differences (p > 0.05) were observed, neither group significantly declined (p > 0.05) in any outcome measure over the 10-week period. No significant (p˃0.05) strength or functional improvements were observed in the CG, though the EG demonstrated significant improvements in their 1RM leg press (p = 0.004) and chest press (p = 0.032), maximal push ups (p = 0.032), and global QOL (p = 0.011). The EG reported a significant increase in fatigue (p = 0.014), while the CG reported significant positive changes in anxiety measures (p = 0.005).

Conclusion

The exercise intervention produced superior improvements in strength and global QOL, compared with the CG. Regardless of group allocation, enrolment in the exercise study appeared to mitigate the treatment-related decline expected in AYA undergoing cancer treatment.

Physical Activity Promotion Programmes in Childhood Cancer Patients and Their Impact on Fatigue and Pain: A Systematic Review

Cancer is one of the main causes of death in children, however, the techniques and interventions applied allow the cure of 80% of diagnosed cases. The aim of this review was to determine the benefits of a health and physical activity promotion programme to reduce pain and fatigue symptoms in children and adolescents with cancer. The databases PubMed, Embase, Scopus, Cochrane, Web of Science and PEDro were searched between December 2020 and January 2021 to elaborate this review, using the keywords child, cancer, exercise, fatigue and pain. The review was preregistered in PROSPERO (ID CRD42021262183). Six studies, out of 937 identified at baseline, were finally included in the review: four randomised controlled trials and two quasi-experimental studies. The total sample size of all the included studies was of 474 participants with very different types of cancer and evolution, and outcome variables were pain, fatigue, physical activity level, self-efficacy and quality of life. A health and physical activity promotion programme seems to improve fatigue in paediatric cancer patients and survivors, but no significant results were found related to pain.

Feasibility and acceptability of a home-based resistance training intervention in adolescent and young adult hematopoietic cell transplant survivors

BACKGROUND

Adolescent and young adult (AYA) hematopoietic cell transplantation (HCT) survivors are at increased risk of metabolic syndrome and lean body mass (LBM) deficits. Resistance training (RT) is a potential intervention to improve LBM, metabolic fitness, and reduce risk of cardiovascular disease.

PROCEDURE

Eligible participants ages 13-39 years, 80-120 days post-HCT, transfusion independent, and prednisone dose ≤1 mg/kg/day were approached. Baseline assessments of body composition (DXA), anthropometrics, and strength testing were completed and participants were taught a 12-week, home-based RT intervention with weekly remote coaching. Follow-up assessments were at day +200 (FU1) and +365 post-HCT (FU2). Feasibility targets were (a) 60% enrollment of approached patients, (b) 80% completion of weekly phone calls, and (c) 80% completion of the RT intervention and FU1 assessments. Acceptability was based on positive responses in qualitative interviews.

RESULTS

Twenty of 31 (65%) eligible AYAs enrolled. Three participants failed to complete baseline measurements (2 = scheduling barriers, 1 = passive refusal) and four participants who completed baseline assessments did not receive the intervention (1 = medical reasons, 2 = no longer interested). Of those who completed baseline assessments, 13 received the intervention, completed 88.5% of coaching calls, and 11 (65%) completed FU1. LBM (kg) increased or remained unchanged in nine of nine participants with complete body composition data at FU1 (mean 1.1 kg; 95%CI: 0.4, 1.9). All participants who completed FU1 reported they would recommend the intervention to an AYA HCT survivor.

CONCLUSIONS

A home-based RT intervention in AYA HCT survivors early post HCT is both feasible and acceptable and may maintain or increase LBM.

A Systematic Review and Narrative Synthesis of Exercise Interventions to Manage Fatigue Among Children, Adolescents, and Young Adults with Cancer

Exercise is known to improve fatigue among adult cancer patients however there is limited understanding of this relationship in children, adolescents, and young adults (AYA) with cancer. The aim is to evaluate the effect of exercise on fatigue outcomes among children and AYA with cancer and to identify important parameters of exercise (frequency, intensity, time, type, and setting), which may be relevant for future intervention design. A systematic search of PubMed, MedLine, CENTRAL, Embase, and Web of Science databases was conducted in December 2019, for studies within the last decade, reporting the effect of exercise on fatigue among cancer patients and survivors 0-24 years of age. Quality assessment was conducted using the Physiotherapy Evidence Database (PEDro) and "Before/After Studies with No Control Group" scales. Seventeen studies (n = 681 participants) were included, of which six were randomized controlled trials (RCTs), and the remaining being pilot (n = 5) or feasibility studies (n = 6). Across studies there was great heterogeneity in intervention delivery, frequency (range: 1-7 days a week), time (range: 10-60 minutes), and duration (range: 3-24 weeks). A positive effect of exercise on fatigue was observed, however, most changes in fatigue were not statistically significant. Exercise is beneficial for reducing fatigue in young cancer patients. However, due to the heterogeneity and quality of existing interventions, firm conclusions about the most effective mode and format of exercise intervention cannot be drawn. There is a need for more definitive large-scale RCTs that can provide data of sufficient quality.
